Created attachment 300979 [details] output from lsbusb -v "ID 0414:a00d Giga-Byte Technology Co., Ltd USB Audio" is the built in motherboard analog jacks on some gigabyte b(450/550) motherboards. The symptom is the headphones create output, but the input (both microphone and line-in) do not work in most applications. This issue occurs in both pulseaudio and pipewire. Trying to solve the issue in wireplumber was [redirected](https://gitlab.freedesktop.org/pipewire/wireplumber/-/issues/268#note_1385274) to ALSA. Disableing using ACP via wireplumber seemed to almost fix the mic-in issue, but completely broke headphones. Attached is the output of lsusb -v

Probably very similar to https://lore.kernel.org/all/20200408140449.22319-1-tiwai@suse.de/ From my naive modifications to that, I have not gotten mic/line-in to work though.
Probably a dupe of https://bugzilla.kernel.org/show_bug.cgi?id=206543, but leaving this open as the thread there has been derailed with off topic issues
My apologies, my link in comment 3 is wrong, this might be a dupe of https://bugzilla.kernel.org/show_bug.cgi?id=206873
Created attachment 300991 [details] alsa-info output
Created attachment 301000 [details] correct alsa info The last attached `alsa-info` was from a modified kernel, this is from a clean install.
Created attachment 301036 [details] Kernel Patch Thi kernel patch is provided by Takashi Iwai Thank you so much for the help! To completely fix the mic another patch is required in userspace here: https://github.com/alsa-project/alsa-ucm-conf/pull/156
The patch was merged to sound git tree, likely included in 5.19-rc1 (via the second pull request).
